Explanation: A river drainage basin is an area drained by a river and all of its tributaries. A river basin is made up of many different watersheds. A watershed is a small version of a river basin. Every stream and tributary has its own watershed, which drains to a larger stream or wetland.
The cyclo-heptatrienyl anion will be considered as antiaromatic compound.
A cyclic compound with a greater energy electron system due to the existence of a 4n delocalized electron is what makes up an anti-aromatic chemical.
Due to its eight pi electrons, the cycloheptatrienyl anion (also known as the tropylium anion) should be antiaromatic; yet, the extra lone pair on one carbon could enable that carbon to become 
hybridized, placing the extra electrons in an orbital. It would become non-planar as well as non-aromatic as a result.
Therefore, the cyclo-heptatrienyl anion will be considered as antiaromatic compound.

Explanation:
Answer:
B. A chemical formula that shows the relative number of each type of
atom in a molecule, using the smallest possible ratio
Explanation:
The empirical formula of a compound shows the relative number of each type of atom in a molecule and it uses the smallest possible ratio.
- It expresses the composition of the compound in the simplest whole number ratio of the atoms of the different elements that makes up the compound.
- To determine empirical formula of a compound , two pieces of information are needed;
- A. mass of each element in the compound
- B. Relative atomic mass of the constituent elements.
Answer:
C
electrons are negatively charged particles
